The Nude Number Story

30 April 2015: I find NumbersAPlenty.com and see nude numbers.

12 May 2015: A co-worker posts an item to their Facebook about a college professor requiring students to take their final exam in the nude. Another co-worker posts a comment about a paper they wrote about nude numbers back in 1985.

15 May 2015: I wrote a program to check if a number is a nude number and added it to the MBNA (MathBabbler Number Analyst). This program is named nude and it was used to help create the Nude Numbers nBAB collection.
